Dash install in 67 Barracuda

I pulled the car apart for the rebuild, now I am getting ready to put it back together. Reading the “install” segment in the factory Barracuda supplement is somewhat helpful, but I have a question not covered in it.

I will have the wipers, heater box and dash wiring installed. Is the dash Installation easier with the instrument bezel & instruments, switched, speaker and glove box installed in the metal dash frame, or do you install the frame and add the various components afterwards?
